White Screen after 4.0 update – No Fixes Working…

Could you try to log in to the site via FTP, delete the existing Jetpack plugin, and install Jetpack 4.0.2 instead?

Let me know if it helps.

If you continue to experience issues, could you add the following to your site’s wp-config.php file?

define('WP_DEBUG', true);

if ( WP_DEBUG ) {

        @error_reporting( E_ALL );
        @ini_set( 'log_errors', true );
        @ini_set( 'log_errors_max_len', '0' );

        define( 'WP_DEBUG_LOG', true );
        define('WP_DEBUG_DISPLAY', false);
        define( 'CONCATENATE_SCRIPTS', false );
        define( 'SAVEQUERIES', true );

}

Once you’ve done so, load your site again, and then check the wp-content/debug.log file for errors. You can paste the results here, and then replace define('WP_DEBUG', true); by define('WP_DEBUG', false); in the code above.

Submitted Support Request at Jetpack.com – no response

Deleted and uploaded new Jetpack – still no change.

Turned Debugging on – no debug log after several reloads.

hm. If you get a white screen and don’t notice anything in debug.log, you’ll need to look at your server error logs to find out more about the error.

If you don’t have access to those yourself, could you ask your hosting provider to take a look, and then paste the results here?

Thanks!

Re-installed Core – Problem solved.

Thank you!
